Protein attributes

Sequence length	278 AA.
Sequence status	Complete.
Protein existence	Inferred from homology

General annotation (Comments)

Function	Involved in the biosynthesis of lipid A, a phosphorylated glycolipid that anchors the lipopolysaccharide to the outer membrane of the cell By similarity. HAMAP-Rule MF_00387
Catalytic activity	(R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] + UDP-N-acetyl-alpha-D-glucosamine = [acyl-carrier-protein] + UDP-3-O-(3-hydroxytetradecanoyl)-N-acetyl-alpha-D-glucosamine. HAMAP-Rule MF_00387
Pathway	Glycolipid biosynthesis; lipid IV(A) biosynthesis; lipid IV(A) from (3R)-3-hydroxytetradecanoyl-[acyl-carrier-protein] and UDP-N-acetyl-alpha-D-glucosamine: step 1/6. HAMAP-Rule MF_00387
Subunit structure	Homotrimer By similarity.
Subcellular location	Cytoplasm By similarity.
Sequence similarities	Belongs to the transferase hexapeptide repeat family. LpxA subfamily.
Sequence caution	The sequence AAL52014.1 differs from that shown. Reason: Erroneous initiation.
